0–100, higher is better. How it is calculated

NORDUnet is a well-established Nordic organization founded in 1985, providing critical network infrastructure and services to over 400 research and education institutions across the Nordic countries. It operates a high-capacity global network connecting national research and education networks (NRENs) in Denmark, Finland, Iceland, Norway, and Sweden, supporting over 1.2 million users. The website reflects a mature, professional entity with comprehensive service offerings and a strong regional presence. Technically, the site is built on WordPress with modern plugins and frameworks, but suffers from slow performance and lacks a valid SSL certificate, which is a significant security concern. Privacy compliance is well addressed with clear policies and cookie consent mechanisms. Overall, the security posture is weak due to missing HTTPS and modern TLS support, which should be prioritized to protect user data and enhance trust. Strategic recommendations include immediate SSL deployment, enabling modern security headers, and improving site performance to align with the organization's reputable business profile.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

5 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

NORDUnet holds a key position as the Nordic gateway for research and education networking, operating on behalf of the five Nordic NRENs. Its business model is non-profit, focusing on providing essential network services, above-the-net services, and logistical support to the academic and research community. The organization benefits from a strong partnership ecosystem including CSC (Finland), DEIC (Denmark), Sikt (Norway), RHnet (Iceland), and Sunet (Sweden). Its market position is solid, supported by a 40-year domain history and consistent branding. The website content and structure target academic institutions, researchers, and education professionals, emphasizing transparency, fairness, and privacy. Growth indicators include active initiatives, events, and publications. The site demonstrates high professionalism and trustworthiness, though technical and security improvements are needed to maintain competitive advantage.

Security posture

The current security maturity of NORDUnet's website is limited by the absence of a valid SSL certificate and lack of HTTPS support, exposing users to potential data interception risks. No modern TLS protocols are enabled, and critical security headers such as HSTS are missing. While SPF records are correctly configured and no subdomain takeover vulnerabilities are present, the overall SSL/TLS configuration is inadequate. No explicit security policy or incident response information is found on the site, indicating potential gaps in transparency and readiness. The cookie consent mechanism and privacy policy demonstrate good GDPR compliance, but the lack of HTTPS significantly undermines data protection efforts. Immediate remediation of SSL/TLS issues is essential to improve the security posture and protect the organization's reputation.

Recommendations

  1. Deploy and maintain a valid SSL/TLS certificate to enable HTTPS across all site pages.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable deprecated protocols to enhance encryption security.
  3. Implement HTTP Strict Transport Security (HSTS) with includeSubDomains and preload options to enforce secure connections.
  4. Add comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy.
  5. Improve website performance by optimizing resource loading and reducing page size to enhance user experience.
  6. Publish a clear security policy and incident response plan with dedicated contact channels to increase transparency and trust.

Technical notes

Notes

The website is built on WordPress using the Elementor page builder and several Jet plugins (JetMenu, JetElements, JetBlog, JetTricks), leveraging jQuery and modern JavaScript libraries such as Swiper and Anime.js. The site is mobile optimized with responsive design and accessibility features. However, the page load time is slow (7.4 seconds) with a large page size (~600 KB) and many resources (145). No valid SSL certificate is installed, and no TLS protocols are enabled, which is a critical technical risk. SEO is well addressed with proper meta tags, Open Graph, and JSON-LD structured data. The technical stack is modern but requires security and performance enhancements to reduce technical debt and improve operational reliability.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
